Lipstick is a general term for all lip makeup. Lipsticks, including lip balm, lip balm, lip gloss, Lip Glaze, etc., can make lips rosy and glossy, achieve hydration, protect lips, increase facial beauty and correct lip contour. It is also a lipstick material for lipstick products, because its structure and function are complex, and its quality is difficult to control.
The lipstick tube is a multi-component combination. Functional packaging composed of different materials is divided into volatile and non-volatile (airtight and non-airtight) according to the material itself. In addition, most of the filling machines are automatic filling machines (direct filling before and after filling, etc.), including the loading of the nozzle tube, which is very complicated, combining different parts, poor tolerance control, or unreasonable design, even if lubricating oil is applied Not the right way. Can cause downtime or malfunction, these errors are fatal.
The ball fork screw is the core part of the lipstick tube, which consists of a ball, a fork, a screw, a ball fork screw and lubricating oil. Kind of like a pump core, but more complicated than a pump core. Some manufacturers boast that the design of non-lubricated ball fork screws is not widely used at present. The standardized drawing of the ball fork screw must be standardized, otherwise the ball fork screw size will be inaccurate. After assembly, there are more complicating factors.
Therefore, it is foreseeable that the injection material must pass the material compatibility verification, otherwise, compatibility problems will occur, and the upper and lower tightening problems will be completed. Ball fork screws are the highest priority. Generally speaking, the alkali will aggravate the problem of iron and heavy iron glue for the purpose of feel, which equals to increasing the risk in the lipstick tube. Also, vibrations during shipping can cause problems with degumming the lipstick tube.
The main quality control indicators of lipstick tubes include feel indicators, filling machine requirements, transportation vibration requirements, air tightness prevention, material compatibility problems, size matching problems, aluminum medium plastic tolerance and color problems, production capacity problems and filling volume satisfaction , the product declared value problem.
